Fax issues using Elastix with an A400P card

Hello all,

I have installed the same Elastix configuration on two machines: One using a Digium TDM400 card and the other one using the OpenVox A400P card.
I started testing the fax receiving functionnality for the two machines by sending faxes from the same number using the same line.
While I am able to receive good quality faxes on the machine using the Digium card, I receive poor quality fax files (lines missing) using the machine with the OpenVox card. Sometimes, the fax is not even detected on the machine using the A400P card and the call is sent to the wrong extension.

Is there any specific modification/configuration I have to perform to solve this problem ?

Moussafir

Forgot to mention the Elastix version used: The latest 2.0

HI,

I would like to connect a fax to FXS and send faxes through the FXO / PSTN port.

Knowing all the difficoulties of faxing over IP I want to share a single PSTN line for incoming calls and for sending with my fax machine (no fax to email).

Does it work this configuration ? I have only one FXO and would like to know if there are any limitations of the card with this configuration before buying.

Is it the A400P fully equivalent to the TDM400 for this purpose ?

Thanks

Thanks for the reply, to avoid well known SIP issues for faxing I was thinking to route outgoing faxes from FXS to FXO on a PSTN line shared with other extensions on the same pbx and avoid all voip limitations for faxing highlighted in the document ... any experience with the A400P to do this ? regards
